So this tent is 10' by 10' correct? How much usable room is in this tent? I have a Double or Queen sized air mattress, will there be room for extras inside? We plan on having a few kids in the near future and don't want to have to replace the tent right away. Just got it and with it being winter can't put it up to check yet.

with any tent, your not going to get the full 10by10, the walls being slanted in cuts of bit of use able space, with a twin and a queen i think you will completely fill the floor of your tent and leave yourself with little to no room for gear etc. a much easier way to go would be you and your wife take the air matress and the kids can sleep on ground pads, which will save alot of room

like the specs say, you will have approx 100+/- Sq.Ft. of "usable space". with this tent you also have the additional storage area in the vestibule area. i have spent time in one however i own mountain hardware and TNF tents. with this tent, it is cool how the poles actually push outward, giving even a bit more room. one thing i would have wanted would be more gear loops inside. hope this helps.

I just received this tent and set it up outside (haven't actually slept in it yet). By my measurements, the interior dimensions seem closer to 9'6" x 9'6". It's 10' x10' if you measure from grommet to grommet on the corner straps. Here's a queen-size sleeping bag, 2 kid sacks, and a pack n play mat. Leaves a little room to walk and maybe some for a dog or your actual luggage. The vestibules are pretty large though.
